50% quartiles of the percentage of the E4 duration consistent with in situ detection of density structures with radial sizes, 2 R_⊙ (green line), 4 R_⊙ (orange line), 6 R_⊙ (red line), and 8 R_⊙ (blue line) as a function of the daily number of released density structures from the equatorial plane for the 1000 Monte Carlo simulations for Scenario 4. The horizontal dashed lines (from bottom to top) correspond to 1, 5, 10, and 20% of the E4 duration.
